Well the glass doesn't have to be colored to have colored fire, but I like the idea. I used to put copper in my fireplace when I lit fires to turn it green. That was before I moved. I forgot what chemical makes it blue, but I know boron makes it red.

We used a gel to make blue fire on camping trips for cooking soup. Using minerals to color fire sounds like an awesome idea.
